The details of construction, arrangement,

and combination of parts constituting my improved tie are as hereinafter described and claimed, reference being had to the accompanying drawing, in which- Figure l is a perspective vien`- of thetie; Fig. Q a horizontal section in two different planes; Fig. 3 a perspective view of one of the metallic reinforcing members; Fig. 4 is an enlarged cross section on jche line 4 4 of Fig. l.

The tie A is oblong and rectangular and provided on its upper side With shoulders a that are separated b v a space sntiicient to receive the base of a railroad rail. In other Words, by means of such shoulders, which are arranged above the: general surface of the tie, I provide rail-seats in which the `ail bases are fitted and held. rl`he tie is provided, in'imediatel)7 belovv the rail-seats, with a transverse hole (1, for receiving bolts that secure the rail fastenings, 'and the tie is further provided, nearer its ends, with other transverse holes u2, that serve for the passage of wires, or small rods, used for controlling the switches, block-signals, etc. l i

of reinforcing members l, which are formed of steel or iron rods provided ivitirenlarged disk-like heads o. These are arranged in sets of tutti', one set being near the bottom of the tie and the other sety near the top thereof, as illustrated in Figs. vl and Lt. These reinforcing members are embedded in the tie in the process of molding, 'and the enlarged he: ds Z) lie within theendsof the. tie, as shown in Fig. 2. These reinforcing members are cheaply produced, and are embedded in the tie in such manner as toreinforce it at points near the top and bottom, Where the tie would be subjected to the The result is that the members B add to the normal or natural strength of the tie so that it is capable of resisting great, strain, due to leverage or to the imposition of Weight. At the same time, the7 do not add to the Weight of the tie a whole, sntlieiently to prevent its being handled -with comparative ease.

VVha't l claim is:

The improved concrete railwaytie formed of concrete, with raised shoulders on 'the upper side which are separated to providef rail-seats, and with transverse openings be'- ,lovvv such rail-scats, for receiving rail-fas tenings, and reinforcing metallic members arranged longitudinally of the tie and in tive horizontal sets or groups, one located near the base and the other near the top of the tie, and comprising metallic rods having end disks which are Wholly embedded in the concrete, substantially as described.
